BPECIFICATION forming part of Letters Patent NO. 357,701, dated February15, 1887.

Application filed May 24, 1686. Serial No. 203,145. (No model.)

To all whom, it may concern.-

Be it known that I, EBER R. CROFUT, a citizen of the United States,residing at Newburyport,iu-the county of Essex and State of Massa.

chusctts, have invented certain new and useful Improvements in Windows;and I do hereby declare the following to be a full, clear, and exactdescription of the invention, such as will enable others skilled in theart to which it appertains to make and use the same, reference being hadto the accompanying drawings, and to letters of reference markedthereon, which form a part of this specification.

This invention relates to improvements in window -sashes constructed andadapted'to turn pivotally in addition to the ordinary slidingmovemenhand is designed to simplify the construction ofsaidpivotally-arranged sashes, and to render the operation thereof morepositive and effective. A further object of the invention is to providemeans upon which the sashes slide as they are raised and lowered,whereby they are prevented from rattling and are made perfectlyair-tight.

The invention consists in the combination and arrangement of partssubstantially as indicated in the drawings, and described and claimedhereinafter.

In said drawings, in 'which similar letters of reference areemployed toindicate corresponding parts, Figure l is an elevation of a window-sashpartly sectionized. Fig. 2 is a longitudinal section of a portion of asash and some of the adjacent parts. Fig. 3 is an elevation of thesupplemental piece or lockingbar strip. Fig. 4 is a section of Fig. 3taken through line 00. Fig. 5 is a perspective view of a device forrepressing the locking-bar. Fig. 6 is a similar view of a binding-plate.Fig. 7 is a perspective view illustrating the relation of the device,shown in Fig. 5 for repressing the locking-bar, to said lockingbar. Fig.8 is a vertical section of two binding plates in operative relation, andFig. 9 is asection taken in the direction of line y, Fig. 2, throughboth window-sashes when down, and a portion of the window-frame.

' In the above-described drawings,a indicates the upright pieces orstiles of the sash; b, the detachable strips or supplemental piecesarranged between the stiles and the jambs b of the Window-frame, and cis a locking-bar arranged in recesses aoin the stiles and detachablestrips respectively. The recess 0 is of sufficient depth to permit thedepression of the bar below the top edge'of the said recess and allowthe rotation of the sash, the opposite recess,a, being designed to allowthe locking-bar to project thereinto so as to cover the joint betweenthe strip and stile,and prevent the turning of the sash when the same isto be locked. The locking-bar is recessed at c", and passes through ahollow head, 6, which is secured to and countersunk in the strip 1), asindicated in Figs. 2 and. 3,and provided with a threaded projection, e,which turns within a correspondingly-threaded collar, 6, countersunk inthe stiles at about the center of the recess therein. A spring, (I, isarranged between the bottom of the recess 0 and the back of thelocking-bar, as shown in Fig. 2, to press said bar into the oppositerecess, a, and across the joint,this being the normal position of thebar. A pin, m, passes through the head-spring and locking-bar, asindicated in Figs. 2, 4, and 7, and holds said parts in their respectivepositions.

To repress the locking-bar back into the recess 0, so that it clears thejoint and leaves the sash free to be turned, I employ a deviceillustrated in Figs. 4, 5, and 7, which consists of an angle-piece, i,secured to or formed on a rod, h, which may project out through the sidepf the head 6 and be provided with a finger-piece, or said rod h may besecured within a sleeve, 9, by a-screw, Z, as in Fig. 4. The angle-piecemoves within the hollow head, and, as it is turned by its operatingfingerpiece, engages with the back of the recess 0 of the locking-barand forces said bar back into the recess 0', as in Fig. 2. While saidbar is recessed at 0 still it isnot absolutely necessary. The recess,however, provides more space for the free movement of the angle-piece,and also permits said bar to project over the top and bottom of the headinto the recess a.

When the improved device is applied to an ordinary window-frame, thedetachable strips slide in the j ambs, as the ordinary window-sash; butto avoid the rattling of the sashes and exclude the air and dampness,which is not secured by the ordinary construction, I have de- ICO visedthe construction illustrated particularly in Figs. 2 and S, in which 1)indicates a grooved or curved strip which is secured to the jamb of thewindow-frame, extending, preferably, the entire length of said jambsbetween the lintel and the sill. Oorrespondingly grooved o1: curvedpieces b are sunk into the strips 1), said pieces being either sectionsarranged at intervals in said strips, as shown in Fig. 2, or a secondcontinuous curved piece extending the entire length of the sash; orstrips may be used, the sections being considered preferable because oftheir producing less friction. The grooved pieces provide ways uponwhich the sashes slide, and, as indicated in Fig. 8, overlap, providinga water-tight joint and also, practically, an airtight joint. \Vhen thesectional curved pieces are used,the entire length of the strips isgrooved to allow the curved strip to project into the strips 1) andcover the joint between said strips and the jamb.

By means of the oppositely-arranged and co-operating ways or curvedsections and strips, which are preferably made of metal, either cast orbent up into the proper form, the usual strip between the sashes may bedispensed with, as the said way prevents any lateral movement of thesashes, and also any rattling or shaking thereof.

To prevent the warping of the sashes and their shrinking away from thedetachable strips 1), I provide metallic pieces 0, formed as indicatedin Figs. 6 and 9, which are secured at the top and bottom of theadjacentfaees or sides of the stiles (t and strips b, and are providedwith portions 1), which engage oppositely, as indicated in Figs. a and9. Should the sashes have a tendency to shrink and to turn pivotally, Ihave provided on the adjacent faces of the portion 1) of the pieces 0 ateat or projection, 1), which engages with a depression in the oppositeportion, of the cooperating piece 0, as indicated in Fig. 9.

As willbe understood,the curved or grooved ways may be applied to anywindow, and are not limited to the device herein shown.

Having thus described my invention, I desire to claim the following:

1. In a window, the combination of oppositely-arranged and cooperatingcurved pieces or strips adapted to be secured to a window sash and jamb,substantially for the purposes herein set forth.

2. In a window, the combination, with a curved metallic strip adapted tobe secured to the window-jamb, of sectional curved metallic piecesadapted to be secured to the stiles of a window-sash and engaging withsaid curved strip, substantially as and for the purposes set forth.

3. The combination, with the j amb of a window and a curved metallicstrip secured thereto, of a window-sash having grooves in the stilesthereof adapted to receive thecurved strip secured to the window -ja|nb,and sectional curved metallic pieces sunk in said grooves in said stilesand engaging with the curved metallic strips, substantially as and forthe purposes setforth.

4. In a window, the combination, with the stiles of apivoted windowsash, and a supplemental or detachable piece or strip arranged adjacentto said stiles, of engaging and co-opcrating pieces arranged in the endsof the adjacent faces of said stiles and strips, for the purposes setforth.

5. In a window, the combination, with the stiles of apivotedwiudow-sash, and a supplemental or detachable strip arrangedadjacent to said stiles, of engaging and co operating pieces secured tothe ends of the adjacent faces of each of said stiles and strips, saidpieces being provided with portions 2, having a teat, p,and areceiving-depression therein, substantially as and for the purposes setforth.

6. The combination, in a window, with the stiles of a sash anddetachable strips, each of which is provided with oppositelyarrangedrecesses a c, a hollow head, 0, and a recessed locking-bar and springarranged in said recesses and passing through said hollow head, of apivotally-arranged angle-piece secured to or formed 011 a rod, h,projecting through said head engaging with saidlocking-bar, said rod 71.being provided with a finger-piece, substantially as and for thepurposes set forth.

In testimony that I claim the foregoing I have hereunto set my hand this17th day of May, 1886.
